[CR]Fertilizer Bomb & Fertilizer Improvements

-Added bags of dry commercial fertilizer.
     These are rather big and heavy, but more common than liquid fertilizer (farms, hardware & garden store).
-Added fertilizer bombs. Recipe uses a source of fertilizer with either sugar or gasoline.
     These are also larger and heavier than most explosives and must be lit.
-Added menu to allow choosing of which fertilizer to use when fertilizing a plot

I would be interested in thoughts on balance, changes to description etc. For example, finding one gallon jug of liquid fertilizer in a store has enough portions to fertilize 60 plots. I did not edit this, but currently I have a much larger and heavier bag of pellet fertilizer having only enough for 20 plots. Nerf it or buff the pellet form?
